AZN vs LIVN

AstraZeneca's deterministic health score is concerning with a Piotroski F-Score of 4/9, indicating marginal financial stability. While profitability metrics like ROE (21.67%) and gross margin (83.26%) are strong, the current price of $92.95 trades significantly above the Graham Number of $45.06, reflecting high growth expectations. Revenue and earnings growth are robust (12% and 78% YoY, respectively), but recent earnings surprises have been volatile, including a -25.9% miss in Q3 2025. Analysts maintain a strong_buy recommendation, though insider selling and weak technical trends (10/100) suggest caution near-term.

LIVN presents a stark contrast between poor deterministic health and strong market momentum. The Piotroski F-Score of 2/9 indicates significant fundamental weakness, and the technical trend is currently bearish. However, the company maintains strong gross margins (68.01%) and a low debt-to-equity ratio (0.36), while analysts remain bullish with a target price of $79.64. The valuation appears attractive on a PEG basis (0.72), but the negative net profit margin and ROE suggest operational inefficiencies or significant non-operating losses.
